Mercedes-Benz Air Conditioning Pressure Sensor 2038211592

Lub siab sensor yog qhov siv ntau tshaj plaws hauv kev ua lag luam, uas yog dav siv nyob rau hauv ntau yam kev lag luam tsis siv neeg tswj ib puag ncig, suav nrog kev txuag dej thiab dej, kev tsheb ciav hlau, cov tsev ntse, kev tswj tsis siv neeg, aerospace, tub rog kev lag luam, petrochemical, roj qhov dej, hluav taws xob. fais fab, nkoj, tshuab cuab yeej, kav dej thiab ntau yam kev lag luam. Thiab nyob rau hauv ib puag ncig sib txawv, ntau hom kev ntsuas siab yuav tsum tau siv kom tsis txhob ua yuam kev.

Cov qauv kev ua haujlwm ntawm qhov sib txawv siab sensors

1. Piezoresistive force sensor: Resistance strain gauge yog ib qho tseem ceeb ntawm piezoresistive strain sensor. Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm cov hlau tsis muaj zog strain gauge yog qhov tshwm sim uas cov strain resistance adsorbed ntawm lub hauv paus cov ntaub ntawv hloov nrog txhua yam deformation, feem ntau hu ua cov nyhuv strain.

2. Ceramic siab sensor: ceramic siab sensor yog raws li piezoresistive nyhuv, thiab lub siab ncaj qha ua rau pem hauv ntej nto ntawm ceramic diaphragm, ua rau me ntsis deformation ntawm lub diaphragm. Thick film resistors yog luam tawm nyob rau sab nraum qab ntawm ceramic diaphragm thiab txuas nrog rau tsim ib tug choj Wheatstone. Vim piezoresistive nyhuv ntawm piezoresistive resistor, tus choj generates ib tug heev linear voltage teeb liab proportional rau lub siab thiab proportional rau lub excitation voltage. Tus qauv teeb liab yog ntsuas raws li 2.0 / 3.0 / 3.3 mv / raws li qhov sib txawv siab.

3. diffused silicon siab sensor: Lub hauv paus ntsiab lus ua haujlwm ntawm diffused silicon siab sensor kuj yog raws li cov nyhuv piezoresistive. Los ntawm kev siv cov nyhuv piezoresistive, lub siab ntawm qhov ntsuas nruab nrab ncaj qha ua rau ntawm lub diaphragm (stainless steel lossis ceramic) ntawm lub sensor, ua rau lub diaphragm los tsim micro-tsav proportional rau lub siab ntawm qhov nruab nrab, thiaj li hais tias tus nqi kuj ntawm lub diaphragm. sensor hloov. Qhov kev hloov pauv no tau kuaj pom los ntawm hluav taws xob hluav taws xob, thiab cov qauv ntsuas teeb liab sib haum rau qhov siab no tau hloov pauv thiab tso tawm.

4. Sapphire siab sensor: Raws li lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm strain resistance, silicon-sapphire yog siv los ua cov khoom siv hluav taws xob semiconductor, uas muaj cov yam ntxwv ntsuas tsis sib xws. Yog li ntawd, lub semiconductor sensor ua los ntawm silicon-sapphire yog qhov tsis hnov ​​​​tsw ntawm qhov kub thiab txias thiab muaj cov yam ntxwv ua haujlwm zoo txawm tias kub kub. Sapphire muaj zog tiv thaiv hluav taws xob; Tsis tas li ntawd, silicon-sapphire semiconductor sensor tsis muaj pn drift.

5. Piezoelectric siab sensor: Piezoelectric nyhuv yog lub hauv paus ntsiab lus ntawm piezoelectric sensor. Piezoelectric sensor tsis tuaj yeem siv rau kev ntsuas zoo li qub, vim tias tus nqi tom qab lub zog sab nraud yog khaws cia tsuas yog thaum lub voj muaj infinite input impedance. Qhov no tsis yog qhov teeb meem hauv kev xyaum, yog li nws tau txiav txim siab tias piezoelectric sensor tsuas tuaj yeem ntsuas qhov kev ntxhov siab dynamic.
